7 Claims. (Cl. 248-120) This invention relates to a container of the crate type and includes a base therefor of pallet-like form whereby the crate. can be transported and stacked by lift trucks such. as those of the lift fork type. The base is of pallet-like form and may be used either with or without crateside walls, in which latter case the deck of the base will aired Stat te crate. Frame memhers 12 of channel form are welded to the rods 10, along lines between adjacent rodsll, while channel members 13 are welded to theundersides of the wires ll andat their ends are welded to the channels 12. 'Thechannels 13 are of somewhat lesser depth than the channels 12, so that the lower surfaces of these various frame is stitfenedland reinforced-by brace bars 14, I5 and serve as the bottomwall of the crate. This application is a modification of and an improvement of'my application Serial No. 301,525, filed Iulyv29, 1952.

One object of my invention is to provide a. container of the character referred towherei'n the base is of such structure that it is highly resistant to bending or distorting under superimposed loads, even though it is supported by feet or legs only at its four corners.

Another object of my invention is to provide a structure wherein the deck of the container base is of welded mesh form, with reinforcingbars orfra'me members variously welded directly to the rods of the wel'dedmesh deck, and wherein the lowermost edges of the frame members are ina common plane, to facilitate insertionof the forks of lifting trucks beneath the container.

A further object of my invention is to provide improved 16 shown more clearly inQFigs. 4,, 8 and 9, the bars 14 extending crosswise of the, deck and heing welded at their ends to the chan'nel's 13.,1The bars 16 bridgethe spaces between the bars1'4j and. are welded at their ends thereto, while the bars 15 extend diagonall'y from the bars 14 to the channels; 12 and 13' at the corners of the deck and are Welded thereto. Allof the bars- 14, 15 and 16 are welded tothe underface of the mesh 1-1-1"2.

Feet 17 are fwelded to the channels 112-13 at the corners ofthe deck and each leg has a depression. or upweirdly-disposed offset recess 18 therein and a toe portion 19 to facilitate stacking of-thebase on another crate as shownin Fig. 1 A web-likestifiener 20 is disposed within each foot and is welded thereto, and gusset plates 21 i are provided at the legs, for greater strength.

and base can accurately and conveniently be positioned r For the smaller size container and where they are not needed for heavy loads, the flat bars 14a and 15a may be used instead of the rectangularly-arranged channel membersIZ and 13, as shown more clearly in Figs. 2a and 3a.

All of' the frame members. I2-131415'-1'6 or I2l13-I4a-I5a14-15'-1"6, as the case may be, are of but two diiferent depths'a's shown in Figs; 5,6, 8' and 9f, "the shallower ones being welded to the lower deck wires and the deeper ones welded'to the upper deck wires, so that not only are both sets'of deck wires directly supported, but the lowermostedg'es .ofthe frame members all occupy a common planegslothat. arms of lift fork trucks can more readily beii nserted beneath the container;

. The vertical walls of' the crate are of lattice or meshlike form, the side walls being. hinged to the deck by helical wires ,22" that. connect the w'alfs to the adjacent frames against superimposed loads than. in the case of various other forms of bases.

a' modification Figs. 5 and6 are end'vi'eWs of the channel frame Inembase of Fig.1, on an en- I marginali wires of the deck.. The oppositely-disposed side walls 23 are hingedly connected to the end walls 24 atdiagonally opposite cornersofthed'eck. by helical wires 25. At the other diagonally-opposite corners of the crate, the

vertical wall's'are detacha'hly connected by latches 26 shown more clearly in Fig/71 The end walls 24 have the loop-like extensions 27 weldedthereto near their mid portions that extend through the deck mesh so as to hold the mid portions of these walls from bulging'under contained loads. 7 At their vertical freeed'ges, the'walls 24 have looplike members 28' welded thereto in position to extend through the mesh openings in. thefwalls 23, for engagement, by slide bolts 29; y I Q I V Each of the bolts 29 has aihandle portion 30 formed 7 thereon for .conve'nientjmanipulation thereof and also serving as a weighted 'elemeiitjtfo hold the bolt against accidental disengagement?frorniheloop 28; A guide 32 of bent-loop form is weldedto the inner faceof the side walls 22 audits looped-'endfsare bent outwardly: to receive the bolt "'29 which is slidable therein. When the" holtis latched with thekeeper 28 as shown in Fig. 7, the weighty handle portion 30 of the bolt will hang downwardly so as to bring a stud 33 that is welded to the bolt into abutting engagement with the adjacent leg of the guide 32. The

.the guide 32.

As shown more clearly in Figs. 2 and 3, lugs 30 are welded to the marginal deck wires so as to prevent displacement of the vertical walls from the deck, as by bulging under internal load pressures when the container walls are in an upright position. The side walls are thus supported directly by the deck at all times. Also, the lugs 31 restrain endwise'rnovement of the side walls.
